CHALK HOLDER AND GUARD.

Specification of Letters Patent.

Patented April 2, 1907.

Application filed April 2, 1906. Serial No. 309,302.

To all whom, it may concern:

Be it known that I, WILLIAM R. LEROY, a citizen of the United States,residing at Oceanpark, in the county of Los Angeles and.

the chalk from being abstracted from the holder and insure that thechalk will remain in the holder until it is sufliciently used up.

. The accompanying drawings illustrate the invention.

Figure 1 is an elevation showing the application of the holder. Fig. 2is a perspective of the holder with the chalk therein. Fig. 3 is avertical section of the holder with the chalk and guard about to beinserted therein. Fig. 4 is a vertical section of the holder with thechalk in place therein. Fig. 5 is aperspective of the guard device forretaining the chalk in the holder.

1 designates the holder, which may consist of any suitable materialsuchas wood, metal, or various alloysand is adapted to be suspended by acord or flexible suspension 2, provided with means 3 for supporting theholder in convenient position for use.

The holder 1 consists of a body having a recess or socket 4 to receivethe chalk 5, the said recess or socket being of any suitable shapecorresponding to that of the chalk. For example, in case of acylindrical chalk said recess would be cylindrical and of a size to fitthe chalk.

The guard device consists of a wire or strip 6, of suitable spring metalbent in staple form, so as to slide, fit, or snap within the socket orrecess 4 in the holder 1, the said socket having preferably an undercutor enlargement 7 at its inner end and the arms 8 of the guard devicebeing bent outward at their inner ends, as shown at 9, to snap in suchengagement. The other ends of said arms 8 are arms spreading by theirown elasticity and being forced in by the wall of the recess to causeengagement of the ends of the arms with the chalk.

In applying the chalk to the holder the guard 6 is placed thereover, asshown in Fig. 3, and the two are pushed together into the recess 4in theholder, the outwardly-bent portions 9 of the guard finally snapping intothe enlargement 7 in the holder and the wall 11 of the recess ridingover the arms 8 of the guard, thereby pressing the same inward andcausing the hooks or inbent portions 10 at the ends thereof to penetratethe chalk or to extend over the end of the chalk, as the case may be.The recess is of such depth that when the chalk is fully pushed in itsouter end will be flush or somewhat below the outer end of the holder,so that there is no way to get any hold on or to draw it out from theholder, and the guard engaging both with the holder and with the chalkeffectually prevents the accidental displacement and also prevents thechalk from being pried out by any person who might be disposed toabstract the same. The inner end of the recess is concaved, as shown at12, so that when the chalk becomes worn quite thin the pressure of thecue thereon will break the chalk and allow the pieces to fall out and bereplaced by a new chalk.

The guard 6 is preferably bent or con caved downward at its middleportion, as shown at 6, so that when the chalk is pushed in the arms 8of the guard will be pushed into the chalk by the straightening of thismiddleportion. The cord 2 is preferably attached to this central part ofthe guard, so that it draws out with the guard, the cord slippingthrough a hole 13 in the neck 1 of body 1.

What I claim is 1. A chalk-holder having a recess to receive and fit thechalk, said recess having an enlargement near its inner end, and anelastic guard device fitting in said recess and bent to engage saidenlargement of the recess and provided with elastic arms, and having aninbent portion to engage the chalk.

2. A chalk-holder comprising a'body having a recess to receive and fitthe chalk and provided With an enlargement near the inner my hand, atLos Angeles, California, this 22d end of saifd recess, a?d a benlt guardif elastic I day of March, 1906. material 'ormed t0 1t and s ide in t erecess 7 and having its arms bent to engage said en- I WVILLIAM LEROX 5largelnent and formed With inbent ends to In presence of engage thechalk.
